Angle NLM is 78 degrees

A way to do this is to find the arc measure of NM and then divide it by 2 to find the angle of NLM

So first subtract

360-110=250

To find the remaining amount of the arc measures. Which is 250 degrees

Next set arc measures NM and ML together to 250 to find what x equals.

14x+16+9x+4=250

Combine like terms

23x+20=250

Subtract 20 from both sides

23x=230

Divide 23 from both sides

x=10.

Then substitute 10 for the equation representing the arc measure of NM.

14(10)+16

140+16

156

The arc measure of NM is 156 degrees


The angle NLM is an inscribed angle. Meaning that it is half of the arc that intersects.

156/2

78

Angle NLM is 78 degrees

Logan is buying equipment for the football team and the baseball team. He spends $40 on football uniforms, and he plans on purch
aleksandr82 [10.1K]

<u><em>Answer:</em></u>

The coordinate pair that represents this solution is (20 , 240)

<u><em>Explanation:</em></u>

<u>We are given that:</u>

1- Equation that represents amount paid on football team based on number of purchased footballs is:

y = 40 + 10x

2- Equation that represents amount paid on baseball team based on number of purchased baseballs is:

y = 200 + 2x

Now, Logan wants to spend the same amount of money on both teams. This means that the y value in both equations should be equal

He also wants to buy the same number of balls for the two teams. This means that the x value in both equations should also be equal.

Therefore, we would be getting the point of intersection between the two equations.

<u>To do this, we will start by equating the two equations and solving for x as follows:</u>

40 + 10x = 200 + 2x

10x - 2x = 200 - 40

8x = 160

x = 20

<u>Then, we will use the x to substitute in any of the two equations:</u>

<u>Substituting in the first equation:</u>

y = 40 + 10x = 40 + 10(20) = 240

<u>Substituting in the second equation (as a check):</u>

y = 200 + 2x = 200 + 2(20) = 240

<u>Based on the above calculations:</u>

If Logan bought 20 balls for each team, he will be spending $240 on each

Solution set is (20, 240)

Note: the graphical solution is attached.

Hope this helps :)

Find the length of an arc of an 8" radius circle if the arc measures 45°. 2 in. 8 in. 16 in.
cricket20 [7]

Answer: 2π inches or 6.28 inches.

Step-by-step explanation:

To solve this problem you must apply the formula shown below:

arclenght=(2r\pi)(C/360)

Where r is the radius and C is the central angle.

Subsitute values. Therefore, you obtain that the length of the arc is:

arclenght=(2(8in)\pi)((45/360)

arclenght=2\pi\ in=6.28in
